摘　　要：用光束法整体平差摄影测量网时，必须妥善解决像片外方位元素以及待定点坐标初始值的求解问题。本文提出了自动逻辑解算多摄站交向摄影测量网中未知数近似值的思想；不同情况下求解像片外方位元素的方法，包括利用部分已知外方位元素的解算方法；以及用空间前方交会解算待定点坐标的实用方法。近似值自动解算程序经过了模拟实验数据和实际数据验算，证明它是可行的；所需地面控制点数少，无需人干预。: In the bundle adjustment of close range photogrammetric network, the determination of approximations for the elements of exterior orientation and the coordinates of object points is necessary in any case. In this paper, the authors have proposed seven available methods for determining exterior orientations under different conditions including the me- thod by using some given elements of exterior orientation and a practical method for de- termining object point coordinates by the use of spatial forward intersection. A computer program can select appropriate methods from them automatically. Having tested by the simulated and practical data, the feasibility of the program has been proved with its advantages of requiring less ground control points and no efforts by operator.
